M39003/01-2985 Equivalent & Substitute Parts

Part Overview

The M39003/01-2985 is a 220 µF hermetically sealed tantalum capacitor rated at 10 V with axial through-hole mounting. Manufactured by Vishay Sprague under the military specification MIL-PRF-39003/1, this component is classified as Active product status with 843 units in current inventory. Substitute parts are necessary when the primary part becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from qualified equivalents meeting identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M39003/01-2985 is determined by the following parameters: capacitance value (220 µF), voltage rating (10 V), tolerance (±10%), mounting configuration (through-hole axial), and operating temperature range (-55°C to 125°C). All listed substitute parts meet these core electrical specifications. Substitutes are grouped into two categories: direct military-grade equivalents maintaining hermetically sealed construction and MIL-PRF-39003/1 compliance, and commercial-grade alternatives offering equivalent electrical performance with different packaging or compliance profiles. Physical dimensions and ESR characteristics may vary within acceptable limits for circuit-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

M39003/01-6043 is a direct equivalent substitute maintaining identical electrical specifications, physical dimensions, and military MIL-PRF-39003/1 compliance. This part is recommended for applications requiring strict military-grade specifications and hermetically sealed construction with no design modifications.

M39003/01-2265 provides electrical equivalence with identical capacitance, voltage, and tolerance specifications. Physical length increases to 0.922" and ESR is specified at 600 mOhm. This part maintains military specification compliance and hermetically sealed construction. Verify PCB layout accommodates the increased axial length before selection.

T322F227K010AT offers electrical equivalence with ROHS3 compliance, making it suitable for applications with RoHS requirements. This commercial-grade molded tantalum capacitor maintains the same electrical parameters but differs in construction type (molded versus hermetically sealed) and physical dimensions (0.300" diameter, 0.710" length). Selection requires confirmation that the application does not mandate military-grade hermetic sealing and that PCB layout accommodates the smaller form factor.

Frequently Asked Questions (FAQ)

Q: Can M39003/01-6043 be used as a direct replacement for M39003/01-2985? A: Yes. Both parts share identical capacitance (220 µF), voltage rating (10 V), tolerance (±10%), physical dimensions (0.351" Dia x 0.786" L), operating temperature range (-55°C to 125°C), and military MIL-PRF-39003/1 specification compliance. No circuit modifications are required.

Q: What is the primary difference between M39003/01-2265 and the main part? A: M39003/01-2265 maintains electrical equivalence but has an increased axial length of 0.922" compared to 0.786" for the main part. ESR is specified at 600 mOhm. Verify PCB layout clearance before substitution.

Q: Is T322F227K010AT suitable for military applications? A: No. T322F227K010AT is a commercial-grade component from the T322 series and does not meet military MIL-PRF-39003/1 specifications. It is suitable only for applications where commercial-grade components are acceptable and RoHS3 compliance is required.

Q: What are the key compatibility criteria for these substitutes? A: All substitutes maintain 220 µF capacitance, 10 V voltage rating, ±10% tolerance, through-hole axial mounting, and -55°C to 125°C operating temperature range. Physical dimensions and construction type (hermetically sealed versus molded) vary and must be verified against PCB layout and application requirements.

Q: Can these parts be used interchangeably in high-reliability applications? A: M39003/01-6043 and M39003/01-2265 maintain military specification compliance and are suitable for high-reliability applications. T322F227K010AT is commercial-grade and requires application-specific evaluation before use in high-reliability contexts.
